Description

Folding camp chair with backrest angle adjustment

The present invention relates to a folding relaxation chair mainly used for leisure in camping grounds or fishing grounds, and more particularly, to facilitate the angle adjustment of the backrest and to prevent an unbalanced load so that a stable angle adjustment is made.

In general, the folding relaxation chair is used for outdoor activities such as camping or fishing, and is made of folding for convenience of storage and movement, and in most cases, it has a structure that is folded in a way that is folded from the four edges to the center.

As shown in Fig. 1, the relaxation chair supports the frame across the front and rear leg rests in an X-shape, and a seat is placed on the frame to provide comfort when the user sits. The advantage of the relaxation chair is to make you feel comfortable when you are seated outdoors. Since there is no function to adjust the angle of the backrest, the structure is designed as ergonomically as possible to make you feel comfortable.

Nevertheless, during outdoor activities, you take several postures, such as when sleeping or eating, and the disadvantage of the relaxation chair is that it does not respond appropriately to such posture changes.

In particular, because the height of the seat is low, the relaxation chair is mainly used with a table with a low height. When eating at the table, there is a problem that the posture becomes rather uncomfortable because you have no choice but to sit with your back off the back.

Therefore, recently, in the Republic of Korea Utility Model Registration No. 20-0476876, Utility Model Registration No. 20-0448230, Patent Publication No. 10-2010-0034425, etc., a chair has been proposed that allows the angle of the backrest to be adjusted using an armrest, but its structure It is different from the relaxation chair, so there is a problem of inferior comfort.

In addition, there is a problem that it is difficult to manipulate the user because the structure is complicated, and the price is higher than that of a general chair, so that it is not universal.

And because the backrest adjustment structure is not sturdy, there is a high risk of being deformed or damaged during use, and there is no safety device due to the occurrence of an unbalanced load, so when the user adjusts the angle of the backrest while sitting, the center of gravity shifts backwards and the center of gravity is disturbed. There is a risk of accidents such as falling over.

The present invention is to solve the above problems, and despite the addition of the backrest adjustment function to the relaxation chair, the backrest adjustment structure has a solid structure, and even when the backrest is tilted back, it is transmitted to the legrest in response to the tilt angle of the backrest. This is to provide a folding relaxation chair with an improved durability of the backrest angle adjustment function by preventing the occurrence of an uneven load due to weight movement by uniformly distributing the resulting load to both left and right sides and front and rear.

The present invention as a technical idea for achieving the above object is composed of a frame covered with a sheet, and the frame is connected to the base frame and the back frame to be foldable, but the leg frame is foldably mounted on the left and right sides of the base, and , The leg frame is folded by the front and rear folding frames that cross each other while connecting the left and right frames, and the seat is mounted over the base frame and the backrest frame to form the base and the backrest. In the above, the backrest frame is equipped with an armrest seated on the upper end of the legrest frame, and the armrest has multi-stage hook grooves so that the seating position of the legrest frame can be adjusted to adjust the angle of the backrest, and the frame is folded. In order to reinforce the rear support of the backrest when adjusting the angle of the backrest using the armrests, post frames are mounted on the left and right sides of the frame to connect the backrest frame and the legrest frame to each other. By allowing the support frames to be connected by intersecting rear folding frames, the backrest angle adjustment function was added to the relaxation chair, and the backrest angle was firmly supported in the state of adjusting the backrest angle.

The folding relaxation chair having the function of adjusting the angle of the backrest of the present invention is a state in which the left and right balance is maintained since the load is uniformly distributed in a cross structure by using the support pillars that support the backrest, and the side load is prevented while the user is seated. Because it is supported stably without shaking, comfort can be improved.

In addition, even when used for a long time, the durability is improved because the frame is less difficult, and the frame can be reinforced by the structural design of the frame, thereby further increasing the user's allowable load and increasing the value of the product.

In addition, despite being a Lilels chair, it can be used with the backrest fully reclined, so it can be used in a variety of postures, and it is not easily deformed or damaged even under heavy loads by inducing the center of gravity to the chair legs in a fully reclined state. And, because it does not fall due to the biased load, safety accidents can be prevented in advance.

In addition, it is convenient to use because the user can change the posture by pulling the backrest forward by pulling the backrest forward or tilting the backrest back by lifting the armrest, so it is convenient to use, and a safety device is provided to keep the unfolded state of the backrest firmly. As well as reinforcing the frame, it can be safely used and prevented from being folded arbitrarily.
